“…Production yield of carbon materials from PE was determined based on thermogravimetric analysis (TGA) result. The value was 47.7%, and it was similar to the production yield of PAN, a reference polymeric carbon precursor, reaching around 50% [31,32]. based on characteristic (002) carbon peak around 25°.…”

Here, we introduce an environmentally friendly way of fabricating carbon nanoparticles which can be utilized as conductive agent for lithium-ion batteries (LIBs). Polyethylene (PE), which comprises the largest portion of plastic waste, was used as a source for carbon nanoparticle synthesis. Sulfonation allowed chemical structural transformation of innately non-carbonizable PE into a carbonizable conformation, and carbon nanoparticles could be successfully derived from sulfonated PE. Then, PE-derived carbon nanoparticles were used as conductive agents for LIBs, and assembled cells exhibited stable performance. Even though the performance is not as good as Super-P, utilization of PE as a source of conductive agent for LIBs might provide an economical advantage to upcycle PE.

“…Recently, organic material–derived carbon nanosheets (CNSs) have been developed for transparent electrode materials for solar cells, transistors, and TEHs. Various organic materials such as polyacrylonitrile, pitch, poly(vinyl alcohol), polyimide, and photoresist have been used to prepare CNSs due to their good film formability, low cost, solution processability, and high carbon content . However, stabilization and additional patterning processes are required to improve carbonization yield and make carbon micropatterns (CMs).…”

In this study, transparent electric heaters (TEHs) are developed based on photoresist‐derived carbon micropatterns (CMs). Well‐defined SU‐8 micropatterns formed by deep UV lithography are carbonized in a tube furnace under an inert atmosphere. The resulting CMs are found to have pseudo‐graphitic structures containing both graphitic and disordered structures. The optical transmittance and electrical conductivity of the CMs increase as their thickness increases. The 102 nm thick CMs exhibit a good transmittance of 78% at 550 nm and a high electrical conductivity of 2.51 × 102 S cm−1. As TEHs, the 102 nm thick CMs demonstrate a maximum temperature of 116 °C with a maximum heating rate of 8.78 °C s−1 at an applied voltage of 60 V and a low electricity consumption of 1.02 W cm−2, which are comparable to the electric heating performance of TEHs prepared with carbon nanomaterials. Therefore, the CMs fabricated in this study can be utilized as electrodes for TEHs in various medical, industrial, consumer, and automobile applications.

“…Conductive nanomaterials including conducting polymers, nanostructured metal composite, and carbon nanomaterials have been studied because of their unique properties. − One-dimensional (1D) conductive nanomaterials have been shown to be particularly effective transducers due to their simple structure and fast directional charge transport characteristics. − Among the 1D materials, carbon nanomaterials are important for electrochemical and biological applications since their surface can be easily modified using a variety of covalent or π-stacking methods. , Especially, carbon nanofibers (CNFs) can be obtained via a simple electrospinning method, which has advantages relatively in terms of efficiency, cost, yield, and reproducibility. Electrospun CNFs are particularly attractive for sensing applications because their electrochemical properties and structures can be easily controlled by varying the process conditions, including temperature, spinning solution component, precursor composition, etc. − However, there remain some challenges such as the production of multidimensional nanofibers requires the optimization of a stable process for electrochemical and structural benefits.…”

Bisphenol A (BPA) is a known endocrine-disrupting compound (EDC) that has a structure similar to that of the hormone estrogen. Even low concentrations of BPA are able to bind estrogen receptors, thereby inducing severe diseases such as reproductive disorders, chronic diseases, and various types of cancer. Despite such serious effects, the use of BPA remains widespread. Therefore, monitoring of both dietary and nondietary exposure to BPA is important for human healthcare. Herein, we present a field-effect transistor (FET) sensor using aptamer-modified multichannel carbon nanofibers (MCNFs) to detect BPA. The MCNFs are fabricated via single-nozzle electrospinning of two immiscible polymer solutions followed by thermal treatment in an inert atmosphere. The MCNFs are then oxidized using a solution of HNO3 and H2SO4 to introduce carboxyl groups on the surface of the fibers. The carboxyl-functionalized MCNFs (CMCNFs) are immobilized on an amine-functionalized electrode substrate by forming a covalent bond, and amine-functionalized BPA-binding aptamers are modified in the same manner on the CMCNFs. The resulting FET sensors exhibit a high sensitivity, as well as specificity toward BPA at an unprecedentedly low concentration of 1 fM. Furthermore, these sensors are stable and could be reused for repeated assays.
